Description
FIELD
[0001] The specification relates generally to immersive environment
systems, and specifically to an immersive environment system having
contact lenses coordinated with images.
BACKGROUND
[0002] Multi-person immersive environments, such as flight
simulators, generally provide the same images for all viewers
within the environment. When the images are adjusted for positions
of the viewers within the environment, each viewer usually wears
special glasses, for example polarized glasses, such that only
images intended for a given viewer are viewed. Such glasses
restrict viewability, however, and further interfere with headsets,
goggles, heads up displays, and the like to be worn in the
immersive environment, as well as non-display elements of the
immersive environment, such as scopes and the like, for example as
part of a flight simulator.
SUMMARY
[0003] In this specification, elements may be described as
"configured to" perform one or more functions or "configured for"
such functions. In general, an element that is configured to
perform or configured for performing a function is configured to
perform the function, or is enabled to perform the function, or is
suitable for performing the function, or is adapted to perform the
function, or is operable to perform the function, or is otherwise
capable of performing the function.

of contact lenses can be marked as associated with a respective set
of images using one or more of text, graphics, RFID (radio
frequency identification) tags and NFC (near field communication)
tags.
[0008] The system can further comprise a first container for the
first pair of contact lenses and a second container for the second
pair of contact lenses, wherein each of the first pair of contact
lenses and the second pair of contact lenses can be marked as
associated with respective images using respective marking on each
of the first container and the second container. Each of the first
container and the second container can comprise one or more of a
contact lens case, an envelope, contact lens packaging, a box, and
a holder.
[0009] The system can further comprise a first viewing position for
viewing the display system using the first pair of contact lenses

station can be marked as associated with respective images using
marks associated with respective contact lens stations.
[0011] Each of the first set of images and the second set of images
can comprise respective stereoscopic images, and each of the first
set of contact lenses and the second set of contact lenses can be
configured to demultiplex the respective stereoscopic images.
[0012] Each contact lens in the first set of contact lenses and the

BRIEF DESCRIPTIONS OF THE DRAWINGS
[0018] For a better understanding of the various implementations
described herein and to show more clearly how they may be carried
into effect, reference will now be made, by way of example only, to
the accompanying drawings in which:
[0019] FIG. 1 depicts an immersive environment system having marked
contact lenses, according to non-limiting implementations.
[0020] FIG. 2 depicts the immersive environment system of FIG. 1,
with contact lenses located at respective viewing stations,
according to non-limiting implementations.
[0021] FIG. 3 depicts a stereoscopic immersive environment system
having marked contact lenses, according to non-limiting
implementations.
[0022] FIG. 4 depicts an alternative immersive environment system
having marked contact lenses, according to non-limiting
implementations.
DETAILED DESCRIPTION
[0023] FIG. 1 depicts an immersive environment system 100,
according to non-limiting implementations. System 100 comprises a
screen 101 and viewing stations 103-1, 103-2 for viewing screen 101
from points of view respective to each of the viewing stations
103-1, 103-2. Viewing stations 103-1, 103-2 will also be
interchangeably referred to hereafter, collectively, as viewing
stations 103 and generically as a viewing station 103. Further,
while two viewing stations 103 are depicted in FIG. 1, in further
implementations system 100 can comprise more than two viewing
stations 103. System 100 further comprises at least one projector
105-1, 105-2 configured to project optically-separable (e.g.
multiplexed) images 106-1, 106-2, 106-3 . . . 106-n (which are
optionally aligned) on screen 101 in at least a one-to-one
relationship with viewing stations 103-1. Projectors 105-1, 105-2
will also be interchangeably referred to hereafter, collectively,
as projectors 105 and generically as a projector 105.
[0024] Optically-separable images 106-1, 106-2, 106-3 . . . 106-n
will also be interchangeably referred to hereafter, collectively,
as images 106 and generically as an image 106. Further, each of
images 106 can comprise a portion of a same scene but adjusted for
viewing from a respective point of view of each of viewing stations
103, as described in further detail below. Further, each individual
image 106 can be projected on a portion of a reflective surface of
screen 101 (the coverage of each projector 105 of screen 101 being
represented by stippled lines) or each individual image can be
projected on about the entire reflective surface of screen 101;
either way, collectively images 106 can be projected on about the
entire reflective surface of screen 101 such that viewers viewing
screen 101 from each viewing station 103 view images 106 on about
the entire reflective surface of screen 101. In other words, each
image 106 can cover a portion of screen 101, but collectively
images 106 cover about the entire reflective surface of screen 101.
As such projectors 105 can be configured for blending images 106
such that the scene projected onto screen 101 is generally
seamless. However, in some implementations, not all viewers to see
the entire surface of screen 101, and hence in these
implementations, not all viewers' content appears on the entire
surface of screen 101; for example, in a simulation where a viewer
is looking out of a small simulated window has a restricted view
and hence only images in the restricted view can be provided.
[0025] Furthermore, images 106 need not be always blended. For
example, in when screen 101 is faceted, an image on each facet need
not be blended into an image on an adjacent facet.
[0026] While each of projectors 105 are depicted as projecting
images 106 onto screen 101 in a front projection configuration,
present implementations are not so limiting and one or more of
projectors 105 can be configured for one or more of rear projection
onto screen 101 and front projection onto screen 101.
[0027] Further, as depicted, system 100 comprises two projectors
105 configured to project the optically-separable images on screen
101. However, in other implementations system 100 can comprise as
few as one projector 105 or more than two projectors: e.g. a
plurality of projectors 105 for projecting images 106 onto about
the entire reflective surface of screen 101.
[0028] Further projectors 105 can be configured to project images
106 on screen by one or more of projecting images 106 concurrently
and alternately. For example, a projector could be driven at about
120 Hz (e.g, 120 images 106 projected per second), but split into
two channels: a first channel for projecting images 106 for viewing
station 103-1 and a second channel for projecting images 106 for
viewing station 103-2. However, projectors 105 can be driven at
other frequencies, including, but not limited to, about 240 Hz
and/or any suitable frequency. Further, projectors 105 could be
stacked for projecting images 106 for more than two viewing
stations. However, the configuration of projectors 105 is generally
appreciated to be non-limiting.
[0029] As depicted, screen 101, viewing stations 103 and projectors
105 are configured for immersive 270.degree. viewing of screen 101.
Indeed, while screen 101 is depicted in partial cross-section, at
least partially surrounding viewing stations 103 on lateral sides,
it is appreciated that screen 101 can extend above and/or over
and/or below and/or under viewing stations 103. However, the
configuration of screen 101 is generally appreciated to be
non-limiting, and can include, but is not limited to one or more of
a flat screen, a faceted screen, a cylindrical screen, a spherical
screen and the like.
[0030] Further, each of viewing stations 103 can comprise a
optional seat for a respective viewer, which, in some
implementations, can slide from a viewer loading position into a
viewing position, such that a viewer can sit in a seat of a
respective viewing station 103, for example, outside of an area
defined by screen 101 and/or a viewing area of screen 101, and
slide the seat into the viewing position such that screen 101 can
be viewed from a given point of view. Further, while a moveable
and/or sliding seat is described, in other implementations the seat
can be in a fixed position.
[0031] System 100 further comprises a plurality of pairs of contact
lenses 107-1, 107-2 in a one-to-one relationship with viewing
stations 103. Pairs of contact lenses 107-1, 107-2 will also be
interchangeably referred to hereafter, collectively, as pairs of
contact lenses 107 and generically as a pair of contact lenses 107.
Each of the plurality of pairs of contact lenses 107 are marked as
associated with a respective viewing station 103. For example, as
depicted, each pair of contact lenses 107 is stored in a respective
container 108-1, 108-2 (referred to interchangeably hereafter,
collectively as containers 108 and generically as a container 108):
container 108-1 is marked with a mark "1" corresponding to viewing
station 103-1; and, container 108-2 is marked with a mark "2"
corresponding to viewing station 103-2. Further, as depicted,
viewing station 103-1 is also marked with a mark "1" and viewing
station 103-2 is also marked with a mark "2". Hence, it is apparent
that pair of contact lens 107-1 is associated with viewing station
103-1 and pair of contact lenses 107-2 is associated with viewing
station 103-2.
[0032] In other words, in depicted implementations, system 100
further comprises respective containers 108 for each of the
plurality of pairs of contact lenses 107, each of the plurality of
pairs of contact lenses 107 marked as associated with a respective
viewing station 103 by a respective mark on the respective
containers 108. Respective containers can comprise one or more of a
contact lens case, an envelope, contact lens packaging, a box, and
a holder.
[0033] However, marking of pairs of contact lenses 107 as being
associated with a respective viewing station 103 can be performed
in any suitable manner. Indeed, each contact lens in a pair of
contact lenses 107 can be marked, rather than a container.
[0034] Furthermore, any mark is within the scope of present
implementations. For example, rather than use numbers such as "1",
"2" etc., natural names and the like can be used for marking,
including, but not limited to "Pilot", "Co-Pilot", "Navigator" and
the like. Further, each viewing station 103 need not be marked with
a mark similar to a corresponding pair of contact lenses 107.
Rather viewing stations 103 can be identifiable as being associated
with a given marked pair of contact lenses 107 via configurations
of viewing stations 103; for example, a viewing station 103 for a
"Pilot" can be identifiable from pilot controls located at the
"Pilot" viewing station 103; similarly, a viewing station 103 for a
"Co-Pilot" can be identifiable from co-pilot controls located at
the "Co-Pilot" viewing station 103; and, a viewing station 103 for
a "Navigator" can be identifiable from navigator controls located
at the "Navigator" viewing station 103.
[0035] Further any suitable words, numbers, letters, graphics etc.
can be used to mark a pair of contact lenses 107 as being
associated with a given viewing station 103. In yet further
implementations wireless marking techniques can be used to mark a
pair of contact lenses 107, including, but not limited to RFID
(radio frequency identification tags) and NFC (near field
communication) tags; in these implementations, system 100 can
further include a wireless tag reader, including but not limited to
an RFID reader and an NFC reader.
[0036] Further, each pair of contact lenses 107 is configured to
separate and/or demultiplex at least one respective image 106,
associated with a given respective viewing station 103 for which a
given pair of contact lenses is marked, from images 106, the at
least one respective image 106 adjusted for viewing from a point of
view of the given respective viewing station 103, as described
below in more detail with reference to FIG. 2.
[0037] Further, each pair of contact lenses 107 can be associated
with a specific viewer. In other words, a pair of contact lenses
107 can be configured for the vision requirements of a specific
viewer, including, but not limited to, a correcting the vision of a
specific viewer (e.g. prescription contact lenses). Alternatively,
each pair of contact lenses 107 can be non-corrective and be
configured for image filtering but not for correcting vision. In
yet a further alternative, each pair of contact lenses 107, while
non-corrective, could be tailored for a comfortable fit for a
viewer: for example pairs of contact lenses 107 and/or each contact
lens in each pair of contact lenses 107 could be provided in one or
more of a small, medium and large size.
[0038] It is further assumed in system 100 that pairs of contact
lenses 107 have been provisioned for storage in a given container
108 and/or previously marked as being associated with a given
viewing station 103. Such provisioning can occur by matching image
filtering capabilities of a pair of contact lenses 107, as
described below with reference to FIG. 2, with an optical scheme of
images 106 associated with a respective viewing station 103.
[0039] System 100 further comprises a computing device 115 in
communication with the at least one projector 105, via a suitable
respective wired and/or wireless links. Computing device 115 is
configured to generate images data for projection by the at least
one projector 105 as images 106. For example, computing device 115
can comprise an image generator, and the like, for generating image
data for producing images 106. Computing device 115 can, in turn,
comprise a processor 120 interconnected with a memory 122 and a
communication interface 124. Processor 120 is generally configured
to generate image data for projection as images 106 by projectors
105 and communicate the image data to projectors via communication
interface 124. Further data for generating the image data can be
stored in memory 122.
[0040] Computing device 115 is further configured for communication
with one or more optional controls 130 via a suitable respective
wired and/or wireless link, controls 130 for controlling images 106
in an immersive environment, computing device 115 and/or projectors
105 further configured to change images 106 in response to
receiving data from controls 130. For example, controls 130 can
comprise a joystick which is used to control images 106 to give the
impression of flying an aircraft and the like: when the joystick is
actuated, images 106 are updated to give the impression of a
aircraft and the like responding to the actuation. However,
controls 130 can include, but is not limited to cockpit controls, a
cockpit mock-up, tank controls, vehicle controls and the like.
While only one set of controls 130 is depicted in FIG. 1 at viewing
station 103-1, in other implementations, system 100 can comprise
controls 130 for two or more viewing stations 103. Further, one or
more viewing station 103 can be identifiable as being associated
with a marked pairs of contact lenses 107 via a configuration of
controls 130, as described above.
[0041] However, it is yet further appreciated that controls 130 are
optional and content of images 106 can be pre-programmed and/or
controlled by an administrator of system 100, and/or by computing
device 115
[0042] In depicted implementations, system 100 further comprising
receivers 150-1, 150-2 for receiving data associated with an
immersive environment. Receivers 150-1, 150-2 will also be
interchangeably referred to hereafter, collectively, as receivers
150 and generically as a receiver 150.
[0043] As depicted, receivers 150 can be in a one-to-one
relationship with viewing stations 103; in other words, each
viewing station 103 can comprise a receiver 150. However, in other
implementations, system 100 can comprise fewer receivers than
viewing stations 103; in other words each viewing station 103 need
not comprise a receiver 150.
[0044] In depicted implementations, each of receivers 150 comprises
headgear configured to be worn by viewers of viewing stations 150.
For example, receivers 150 can include, but are not limited to,
helmets, microphones, speakers, headsets, heads-up displays, and
the like. As such, receivers 150 can receive data from computing
device 115 associated with images 106, for example audio data for
providing aural information associated with images 106 and/or
visual data for providing visual information associated with images
106, for example on a heads-up display. In other words, receivers
150 are generally used in an immersive environment to simulate a
physical real-world environment, such as a headgear that would be
worn in a real-world cockpit. As such, use of special glasses for
viewing images 106 respective to each viewing station 103 would
physically interfere with receivers 150.
[0045] In some implementations, system 100 can further comprise
viewing apparatus for use by a viewer (e.g. a gun mount, an optical
measurement apparatus and the like) which, while not worn by a
viewer, can be physically interfered with by glasses.
[0046] Use of contact lenses 107 mitigates such physical
interference, such that a viewer of a viewing station 103 and/or a
receiver 150 can use contact lenses 107 to view images 106 without
having to worry about contact lenses 107 physically interfering
with a receiver 150. However, as images 106 are provided respective
to each viewing station 103, it is important to coordinate contact
lenses 107 with viewers of each viewing station 103.
[0047] For example, attention is directed to FIG. 2, which depicts
a subset of elements of system 100 with pairs of contact lenses 107
located at respective viewing stations 103. It is appreciated that
while not all elements of system 100 are depicted in FIG. 2 for
clarity (e.g. the links between controls 130, receivers 150 and
computing device 115), they are nonetheless present.
[0048] It is further appreciated that, in FIG. 2. each respective
pair of contact lenses 107 has been issued to a respective viewer
of a viewing station 103 by matching a mark associated with each
pair of contact lenses 107 with a respective viewing station 103,
such that images 106 associated with a respective viewing station
103 are viewable from the respective viewing station 103 using a
respective pair of contact lenses 107. For example, pair of contact
lenses 107-1 has been issued to a viewer (not depicted) of viewing
station 103-1 by matching the mark "1" at container 108-1 with the
mark "1" of viewing station 103-1. Similarly, pair of contact
lenses 107-2 has been issued to a viewer (not depicted) of viewing
station 103-2 by matching the mark "2" at container 108-2 with the
mark "2" of viewing station 103-2. However, as described above, an
association between a given marked pair of contact lenses 107 and a
given viewing station 103 is not limited to matching identical
marks at each.
[0049] In any event, each of images 106 comprise one or more of a
colour scheme and a polarization scheme respective to an associated
viewing station 103, and respective pairs of contact lenses 107 are
configured to separate and/or demultiplex at least one respective
image 107 based on one or more of the colour scheme and the
polarization scheme.
[0050] For example, in some implementations, each of the plurality
of pairs of contact lenses 107 comprises a respective polarizer for
separating at least one respective image 106 associated with a
given respective viewing station 103, from images 106. Such
polarizers can comprise one or more of linear polarizers, circular
polarizers and the like. Hence, a subset of images 106 are
configured to be demultiplexed d from images 106 with polarizers at
pair of contact lenses 107-1, while a different subset of images
106 are configured to be demultiplexed from images 106 with
polarizers at pair of contact lenses 107-2. For example, as
depicted, pair of contact lenses 107-1 are configured to
demultiplex images 106-1, 106-3 from images 106 and pair of contact
lenses 107-2 are configured to demultiplex images 106-2, 106-n from
images 106. In other words, a polarization state of each of images
106-1, 106-3 is similar to a polarization state of a polarizer at
pair of contact lenses 107-1, while a polarization state of each of
images 106-2, 106-n is different from a polarization state of a
polarizer at pair of contact lenses 107-1. Hence, images 106-1,
106-3 are transmitted through pair of contact lenses 107-1 while
images 106-2, 106-n are generally blocked from being transmitted
through pair of contact lenses 107-1; similarly, images 106-2,
106-n are transmitted through pair of contact lenses 107-2 while
images 106-1, 106-3 are generally blocked from being transmitted
through pair of contact lenses 107-2. However, it is appreciated
that blocking transmission can include attenuation of images 106
such a portion of a "blocked" image can still be partially
transmitted.
[0051] It is further appreciated that images 106-1, 106-3
configured to be viewed from viewing station 103-1 and images
106-2, 106-n are configured to be viewed from viewing station
103-2. Hence, when a pair of contact lenses 107 associated with a
respective viewing station 103 is issued to a viewer of a different
viewing station 103, images 106 other than those intended to be
viewed at the respective viewing station 103 will viewed; as pairs
of contact lenses 107 cannot be easily exchanged between viewers,
it is important in system 100 that each pair of contact lenses 107
be issued to a viewer of a corresponding viewing station 103, which
is accomplished via marking of pairs of contact lenses 107.
[0052] It is further appreciated that images 106 could be
reconfigured such that content initially in images 106 for viewing
at viewing station 103-1 via contact lenses 107-1 can be changed to
images 106 for viewing at viewing station 103-2 via contact lenses
107-2, for example if contact pairs of contact lenses 107 are
incorrectly issued. However, such switching is again inconvenient
and requires an administrator of system 100 to reconfigure images
106, which can further be time consuming and inefficient.
[0053] It is further appreciated that each subset of images 106
viewable via a given pair of contact lenses 107 generally provides
full coverage of screen 101 such that a viewer at a given viewing
station 103 is provided with a full immersive environment and/or
field of view from the point of view of the given viewing station
103. A viewer at another given viewing station 103 is also provided
with a full immersive environment and/or field of view from the
point of view of the another given viewing station 103, via another
subset of images 106 which are adjusted for the point of view of
the another given viewing station 103. Hence, for example, a viewer
at a "Co-Pilot" viewing station 103 will see the same scene as a
viewer at a "Pilot" viewing station 103, but adjusted for the
perspective of the "Co-Pilot" viewing station. This can be
extremely important when objects in images 106 are depicted as
close to each of viewing stations 103 as small changes in
perspective can result in large changes in how the object is
depicted and/or viewed.
[0054] However, present implementations are not so limiting and
each subset of images 106 need not show the same scene. For
example, each of the "Pilot" and "Co-Pilot" can be "looking" out of
different windows in a simulated aircraft (e.g. one could be
looking out the front of the aircraft and the other out the rear of
the aircraft) and hence each subset of images 106 can show
different scenes. Furthermore, each subset of images 106 can
comprise completely different scenes such that system 100
effectively provides two different simulations simultaneously. In
other words, subsets of images 106 can be related or unrelated as
desired.
[0055] It is yet further appreciated that perspective in images 106
can be critical. For example, in some implementations, system 100
can comprises measurement tools for use by a viewer at a viewing
station 103, for example to take "measurements" of a simulated
scene in images 106; the measurement tools can require a view in
images 106 to be provided at a given level of precision and/or a
given resolution for an accurate measurement to be made. However,
such perspective and/or accuracy is not to be understood as
particularly limiting and can be customized for a given
simulation.
[0056] It is further appreciated that while only two images 106 are
depicted in each subset as being filtered for each pair of contact
lenses 107, any number of images 106 can be filtered by each pair
of contact lenses 107, and projected by any of projectors 105, to
provide: a. about full coverage of screen 101 for a given viewer at
a given viewing station 103; and b. a stream of images 106 to
provide an immersive environment.
[0057] Alternatively, rather than polarizers, each of the plurality
of pairs of contact lenses 107 can comprise a respective colour
filter for separating the at least one respective image 106,
associated with a given respective viewing station 103, from images
106. In other words, each of images 106 can comprise a respective
colour scheme that is viewable through a respective pair of contact
lenses 107 comprising a respective colour filter for filtering the
respective colour scheme. Such colour filters can comprise one or
more of optical notch filters, optical multi-notch filters, optical
bandpass filters and the like. For example, each of images 106-1,
106-3 can comprise wavelengths and/or colours within given
wavelength ranges transmittable by a colour filter at pair of
contact lenses 107-1, but not transmittable by a colour filter at
pair of contact lenses 107-2; similarly, each of images 106-2,
106-n can comprise wavelengths and/or colours within certain ranges
transmittable by a colour filter at pair of contact lenses 107-2,
but not transmittable by a colour filter at pair of contact lenses
107-1.
[0058] It is yet further appreciated that while pairs of contact
lenses 107 are presently described as comprising passive polarizing
filters and/or passive colour filters, in other implementations,
filters at pairs of contact lenses 107 can be active filters. For
example, filters at each pair of contact lenses 107 can comprise
liquid crystal shutters which can be opened and closed for
alternating viewing of images 106, the projection of images 106 for
a given pair of contact lenses 107 coordinated with opening and
closing the liquid crystal shutters.
[0059] However, it is yet further appreciated that other optical
filters for demultiplexing images 106 is within the scope of
present implementations.
[0060] Regardless of how images 106 are filtered by pairs of
contact lenses 107, when a user (i.e. a viewer) of a viewing
station 103 is to use system 100, the viewer first determines which
given viewing station 103 they will be using, and then determines
which pair of contact lenses 107 corresponds to the given viewing
station 103 they will be using via marking of the pairs of contact
lenses 107. The viewer then insert a pair of contact lenses 107
respective to the given viewing station 103, and then moves to the
given viewing station 103 to begin viewing images 106 respective to
the given viewing station 103; a receiver 150 respective to the
given viewing station 103 can be worn, pairs of contact lenses 107
not physically interfering therewith. It is further appreciated
that this procedure can be repeated for each viewer of each viewing
station 103, the marking of pairs of contact lenses 107 ensuring
that the appropriate contact lenses 107 are worn.
[0061] In depicted implementations, each of images 106 are
monoscopic and each contact lens in a respective pair of contact
lenses 107 is configured to demultiplex a same respective image 106
from images 106. In other words, each contact lens of a pair of
contact lenses 107 is configured to transmit the same images, and
images 106 are viewed monoscopically.
[0062] However, attention is next directed to FIG. 3 which depicts
a system 100a, similar to system 100, with like elements having
like numbers. However, system 100a comprises projectors 105a-1,
105a-2 configured to project optically-separable (and optionally
aligned) stereoscopic images 106a-1, 106a-2, 106a-3 . . . 106a-n,
which are separable via pairs of contact lenses 107a-1L, 107a-1R,
and 107a-2L, 107a-2R.
[0063] Projectors 105a-1, 105a-2 will also be interchangeably
referred to hereafter, collectively, as projectors 105a and
generically as a projector 105a. Optically-separable images 106a-1,
106a-2, 106a-3 . . . 106a-n will also be interchangeably referred
to hereafter, collectively, as images 106a and generically as an
image 106a. Pairs of contact lenses 107a-1L, 107a-1R, and 107a-2L,
107a-2R will also be interchangeably referred to hereafter,
collectively, as pairs of contact lenses 107a and generically as a
pair of contact lenses 107a.
[0064] System 100a can further comprises a computing device 115a in
communication with projectors 105a, controls 130 and receivers 150
(though links between computing device 115a, controls 130 and
receivers 150 are not depicted for clarity), which in turn
comprises a processor 120a, similar to processor 120, a memory
122a, similar to memory 122, and a communication interface 124a,
similar to interface 124. Indeed, computing device 115a is
generally similar to computing device 115, however computing device
115a is configured to provide stereoscopic image data to projectors
105a; similarly, projectors 105a are similar to projectors 105,
however projectors 105a are configured to receive stereoscopic
image data and project stereoscopic images 106a onto screen
101.
[0065] However, any suitable computing device, and/or any suitable
number of computing devices, could be used to control system 100a
(and/or system 100). For example each projector 105a can include a
computing device and/or a separate computing device could be used
to provide images for each contact lens in each pair of contact
lenses 107a. Indeed, a number and type of computing devices is not
to be considered particularly limiting.
[0066] Further, pairs of contact lenses 107a are initially stored
in respective containers 108a-1L, 108a-1R, 108a-2L, 108a-2R, which
will also be interchangeably referred to hereafter, collectively,
as containers 108a and generically as a container 108a, similar to
containers 108.
[0067] In any event, in these implementations, pairs of images 106a
form stereoscopic images, but are otherwise similar to images 106.
Further, a first contact lens 107a in a respective pair of contact
lenses 107a is configured to demultiplex a left eye stereoscopic
image 106a from images 106a, and a second contact lens in the
respective pair of contact lenses 107a is configured to demultiplex
a right eye stereoscopic image from images 106a. Each of the first
contact lens and the second contact lens is further marked as for a
left eye and right eye, respectively. Pairs of contact lenses 107a
are otherwise similar to pairs of contact lenses 107.
[0068] For example, as depicted: of a pair of contact lenses
107a-1L, 107a-1R, first contact lens 107a-1L, initially stored in
container 108a-1L, is configured to demultiplex a left eye
stereoscopic image 106a-1 from images 106a; and, second contact
lens 107a-1R, initially stored in container 108a-1R is configured
to demultiplex a right eye stereoscopic image 106a-3 from images
106a. Similarly, of a pair of contact lenses 107a-2L, 107a-2R,
first contact lens 107a-2L, initially stored in container 108a-2L,
is configured to demultiplex a left eye stereoscopic image 106a-2
from images 106a; and, second contact lens 107a-2R, initially
stored in container 108a-2R is configured to demultiplex a right
eye stereoscopic image 106a-n from images 106a.
[0069] In other words, system 100a is similar to system 100,
however pairs of stereoscopic images 106a respective to a point of
view of each viewing station 103 are projected, rather than
monoscopic images as in system 100; further contact lenses 107a are
each configured to demultiplex images respective not only to an
associated viewing station 103, but also for left eye of a viewer
or a right eye of a viewer of the given viewing station 103. Hence,
marking of each contact lens 107a is even more important than in
system 100.
[0070] As such, each of first contact lenses 107a-1L, 107a-2L are
marked as for a left eye via respective marks "1-L", "2-L" at
containers 108-1L, 108-2L, and each of second contact lenses
107a-1R, 107a-2R are marked as for a right eye via respective marks
"1-R", "2-R" at containers 108-1R, 108-2R. In other words "1"
indicates that a contact lens 107a is to be used with a viewing
station 103a that is similarly marked with "1", "2" indicates that
a contact lens is to be used with a viewing station 103a that is
similarly marked with "2", "L" indicates that a contact lens 107a
is to be used with left eye, and "R" indicates that a contact lens
107a is to be used with a right eye. Such marking of contact lenses
107a enables not only the appropriate pair of contact lenses 107a
to be used with a given viewing station 103, but also enables each
contact lens 107a to be used with an appropriate eye at the given
viewing station 103a.
[0071] Persons skilled in the art will appreciate that there are
yet more alternative implementations and modifications possible.
For example, while not depicted, in some implementations, either of
system 100 (and/or system 100a) can further comprise contact lens
stations in a one-to-one relationship with the plurality of pairs
of contact lenses 107, each of the contact lens stations configured
for one or more of issuing a respective pair of contact lenses 107
for a given respective viewing station 103 and inserting the
respective pair of contact lenses 107 into eyes of a user of the
given respective viewing station 107. For example, each respective
contact lens station can comprise faucets, a sink and plumbing
facilities therefore for washing hands and the like, and a mirror
for assisting in inserting pairs of contact lenses 107 into an eye
of user of the given viewing station 107.
[0072] Further, in these implementations, each of the plurality of
pairs of contact lenses 107 are marked as associated with a
respective viewing station 103 by a respective mark on a respective
contact lens station, similar to marks "1" and "2" described above.
Hence, when a user of a viewing station 103 is to use system 100,
the viewer first determines which given viewing station 103 they
will be using, and then determines which contact lens station
corresponds to the given viewing station 103 they will be using via
marks at the contact lens stations. It is appreciated that each
contact lens station is provisioned with one or more pairs of
contact lenses 107 respective to corresponding viewing stations
103. The viewer then uses the contact lens station to receive and
insert a pair of contact lenses 107 respective to the given viewing
station 103, and then moves to the given viewing station 103 to
begin viewing images 106 respective to the given viewing station
103; a receiver 150 respective to the given viewing station 103 can
be worn, pairs of contact lenses 107 not physically interfering
therewith. It is further appreciated that this procedure can be
repeated for each user of each viewing station 103, the marking of
pairs of contact lenses 107 ensuring that the appropriate contact
lenses 107 are worn.
[0073] While FIGS. 1 to 3 have been described with respect to
viewing stations 103 and a projection display system, present
implementations are not so limited. For example, attentions is next
directed to FIG. 4 which depicts a system 100b similar to system
100, with like elements having like numbers with a "b" appended
thereto. System 100b comprises: a display system 401 configured to
display multiplexed images 106b comprising at least a first set of
images 106b-1, 106b-3 and a second set of images 106b-2, 106b-n
optically-separable from the first set; a first pair of contact
lenses 107b-1 marked as associated with the first set of images
106b-1, 106b-3 and configured to demultiplex the first set from the
second set; and, a second pair of contact lenses 107b-2 marked as
associated with the second set of images 106b-2, 106b-n and
configured to demultiplex the second set from the first set. It is
appreciated that images 106b-1, 106b-2, 106b-3, 106b-n are
interchangeably referred to collectively as images 106b and
generically as an image 106b. First pair of contact lenses 107b-1
and second pair of contact lenses 107b-2 are hereafter
interchangeably referred to collectively as pairs of contact lenses
107b (and/or contact lenses 107b) and generically as a pair of
contact lenses 107b.
[0074] Similar to contact lenses 107 described above, the first set
of images 106b-1, 106b-3 and the second set of images 106b-2,
106b-n are optically separable and/or multiplexed via one or more
of different respective colour schemes and different respective
polarization schemes. Further each of the first pair of contact
lenses 107b-1 and the second pair of contact lenses 107b-2 comprise
one or more of different respective colour schemes and different
respective polarization schemes for respectively demultiplexing the
first set of images 106b-1, 106b-3 from the second set of images
106b-2, 106b-n, and the second set of images 106b-2, 106b-n from
the first set of images 106b-1, 106b-3.
[0075] Each of first pair of contact lenses 107b-1 and second pair
of contact lenses 107b-2 can be marked as associated with a
respective set of images using one or more of text, graphics, RFID
(radio frequency identification) tags and NFC (near field
communication) tags, as described above. As depicted, system 100
further comprises a first container 108b-1 for the first pair of
contact lenses 107b-1 and a second container 108b-2 for the second
pair of contact lenses 107b-2, and each of first pair of contact
lenses 107b-1 and second pair of contact lenses 107b-2 are marked
as associated with respective images 106b using respective marking
on each of first container 108b-1 and second container 108b-2.
Specifically, container 108b-1 is marked with a "1" indicating
first pair of contact lenses 107b-1 contained therein is associated
with first set of images 106b-1, and container 108b-2 is marked
with a "2" indicating second pair of contact lenses 107b-2
contained therein is associated with second set of images
106b-2.
[0076] Each of first container 108b-1 and second container 108b-2
can comprise one or more of a contact lens case, an envelope,
contact lens packaging, a box, and a holder, similar to containers
108.
[0077] In contrast to systems 100, 100a, system 1001) need not
comprise projector display system (including a screen), though
display system 401 could comprise a projector display system.
Indeed, display system 401 can comprise one or more of a projector
display system, a flat panel display system, a tiled display
system, a cathode ray display system, an LCD (liquid crystal
display) system, an OLED (organic light emitting diode) display
system, and the like. When display system 401 comprises a projector
display system, display system 401 comprises a projector and a
screen upon which the projector projects first set of images
106b-1, 106b-3 and second set of images 106b-2, 106b-n, similar to
system 100.
[0078] However, as depicted, display system 401 comprises a flat
panel display system.
[0079] Regardless, display system 401 is configured to generate the
multiplexed images 106b one or more of concurrently and
alternately, as in system 100.
[0080] Also similar to system 100, system 100b further comprises a
computing device 115b configured to generate multiplexed images
106b for display by display system 401. Indeed, computing device
115b is in communication with display system 401 and comprises a
processor 120b, a memory 122b, and a communication interfaces 124b,
each respectively similar to processor 120, memory 122 and
interface 124. It is yet further appreciated that, in some
implementations; computing device 115b can be incorporated into
display system 401.
[0081] Regardless of a configuration of display system 401, it is
appreciated that system 100b comprises an immersive environment
and/or a simulation environment such that viewers using contact
lenses 107b-1, 107b-2 to view images 106b at display system 401,
are appreciated to be participating in a simulation, for example a
cockpit simulation and the like.
[0082] However, in further contrast to system 100, system 100b does
not necessarily comprise viewing stations. Rather, system 1001) can
comprise a first viewing position 403-1 for viewing display system
401 using first pair of contact lenses 107b-1 and a second viewing
position 403-2 for viewing display system 401 using second pair of
contact lenses 107b-2, wherein each of first pair of contact lenses
107b-1 and second pair of contact lenses 107b-2 are marked as
associated with respective images using marks associated with
respective viewing positions 403-1, 403-2 (viewing positions 403-1,
403-2 interchangeably referred to hereafter collectively as viewing
positions 403 and generically as a viewing position 403). For
example the mark "1" at container 108b-1 can correspond to viewing
position 403-1 and the mark "2" at container 108b-2 can correspond
to viewing position 403-2.
[0083] It is appreciated that viewing positions 403 need not be a
specific area in front of display system 401, but simply comprise a
starting position for a viewer wearing corresponding pairs of
contact lenses 107b. Indeed, in some implementations, system 100b
can further comprise apparatus (not depicted) for tracking one or
more of a position of a viewer and headtracking of a viewer
relative to display system 401, though, in general, system 100b is
configured to determine a first position of each of viewers wearing
contact lenses 107b. Hence, each of first viewing position 403-1
and second viewing position 403-2 can be mobile, in that once a
first position of each of viewers is determined, the viewer can
move relative to display system 401; images 106b can be adjusted
accordingly to correct for perspective of a viewer as a viewing
position 403 and/or a viewer changes. However, it is appreciated
that first viewing position 403-1 and second viewing position 403-2
need not be fixed positions; indeed, in some implementations, such
viewer tracking does not require viewers to be in any type of
starting position. Rather, tracking can be active and/or marked. As
such, tracking apparatus can determine which position is being
tracked based on, for example, an identifier in tracking
signals.
[0084] Alternatively, system 100b can be similar to system 100 and
each of first viewing position 403-1 and second viewing position
403-2 can comprise one or more of a viewing station, seat, controls
for controlling the multiplexed images in an immersive environment
and receivers for receiving immersive environment data, as
described above.
[0085] In yet further implementations, system 100b can further
comprise a first contact lens station and a second contact lens
station, as described above, each configured for one or more of
issuing a respective pair of contact lenses 107b and inserting a
respective pair of contact lenses 107b into eyes of a viewer,
wherein each of the first contact lens station and the second
contact lens station are marked as associated with respective
images 106b using marks associated with contact lens stations. In
other words, marks "1" and "2" can be provided at the contact lens
stations rather than on a container 108b.
[0086] As described above with respect to images 106a, each of the
first set of images 106b-1, 106b-3 and second set of images 106b-2,
106b-n can comprise respective stereoscopic images, and each of
first set of contact lenses 106b-1 and second set of contact lenses
106b-2 can be configured to demultiplex the respective stereoscopic
images. Hence, in these implementations, each contact lens 107b in
the first set of contact lenses 107b-1 and the second set of
contact lenses 107b-2 can be further marked as associated with one
of a right eye and a left eye.
[0087] Alternatively, images 106b can be similar to images 106 and
hence each of the first set of images 106b-1, 106b-3 and second set
of images 106b-2, 106b-n can comprise respective monoscopic images.
In these implementations, each of first set of contact lenses
107b-1 and second set of contact lenses 107b-2 are configured to
demultiplex the respective monoscopic images 106b.
[0088] Also similar to images 106 described above, in some
implementations, each of first set of images 106b-1, 106b-3 and
second set of images 106b-2, 106b-n can comprise a similar scene.
In some of these implementations, the similar scene can be rendered
at different perspectives accounting for the different angles in
which viewers are viewing display system 401 from different viewing
positions 403. However, in other implementations, first set of
images 106b-1, 106b-3 and second set of images 106b-2, 106b-n can
comprise a different scene, such that system 100 can provide two
different simulations which can be related (e.g. front and rear
views from an airplane) or unrelated.
[0089] Hence, in general, by providing contact lenses, rather than
glasses, for viewing and filtering images in an immersive
environment, a more realistic viewing experience can be provided,
without interference by the viewing apparatus, i.e. the contact
lenses. For example, contact lenses do not interfere with other
